## How to call it through Zero

zero fetch --capability japanese-address-normalizer-e37feabe -d '<json body>'
```

Example prompt: Can you normalize this Japanese address into clean prefecture, city, town, and chome-banchi parts, fix any fullwidth digits or old kanji, and give me the postal code and confidence score? The address is: '東京都渋谷区道玄坂１－２－３'.

## When to prefer this

Use this endpoint when you need to normalize, validate, or deduplicate Japanese addresses before storage or comparison, especially when input may contain mixed fullwidth/halfwidth characters, old-form kanji, or inconsistent chome-banchi notation. Prefer this over a postal code lookup endpoint when you have a full address string (not just a postal code) that needs to be parsed and cleaned.

## Known failure modes

- Address string is empty or exceeds 200 characters — validation error returned
- Address is not recognizable as a Japanese address — low confidence score or parsing failure
- Ambiguous address with multiple possible interpretations — low confidence score returned
- Malformed request body — HTTP 400 error
- Payment not included or invalid x402 payment — HTTP 402 error

## How this service works

Japanese address normalization (住所正規化): standardize a JP address into clean prefecture / city / town / chome-banchi components. Fixes fullwidth/halfwidth digits, old-form kanji, and chome-banchi notation variants, and resolves the 7-digit postal code. Returns a 0-1 confidence score so agents can flag low-quality input. Use for address validation, cleansing, deduplication, and canonicalization before storage or comparison.

## Output

Returns structured address components (prefecture, city, town, chome-banchi), a resolved 7-digit Japanese postal code, and a 0–1 confidence score indicating input quality. Allows agents to detect low-quality or ambiguous addresses and decide whether to flag them for review.
